Human Metamorphosis, a satirical Manga depicting human society compared to the insect world, focuses on the life of a devious woman. Tomura Toshiko, who is said to be a genius, is a rising star writer. Her novel wins the Akutagawa Prize for the best novel of the year. While she attends the award ceremony, another woman named Usuba Kageri commits suicide in another place. It turns out that Kageri and Toshiko used to live together, and the awarded novel was copied from Kageri's transcript. Toshiko is like a parasite: approaching talented people one after another, squeezing everything out of them and stealing their works for her own fame. Behind her success story, she has her secrets.
